Sooo..... What would you pay to have a Revit model on site on your iPhone? This is in no way a farce. I saw this myself and it's pretty amazing! Ian wrote a custom exporter for Revit to break the model down into smaller chunks the iPhone could handle. It's still only working on his phone but with a little more work he may be ready to launch an Alpha/Beta soon.
Check out the post of this working prototype on the forum.
